3 Claims.

This invention relates to new and improved coke oven design and equipment for use in connection with coke ovens. More particularly the invention relates to coke ovens of the character having relatively wide, fiat floors, with part or ill of the heat for coking supplied through the cor.

These ovens may be operated for the purpose of coking liquid hydrocarbons, such as tars, pitches, heavy petroleum residues or the like, or

may be used for coking solid fuel such as coal. A

further use for such ovens is in coking a liquid or semi-liquid mass which contains both liquid hydrocarbons and entrained solid matter, such as coal.

In order to properly quench the coke and also reduce breakage of the coke when pushed from the oven, we provide a tray of substantially the same area 'as the oven floor, this tray receiving 0 the coked layer as it is pushed from the oven.

The coke is preferably quenched in the tray and the tray is then tilted to discharge the quenched coke into cars or other receptacles.

It is an object of the present invention to pro- 5 vide a new and improved coke oven construction and new and improved operating mechanisms for use therewith.

It is also an object to provide a mechanism for receiving and quenching the pushed charge of 30 coke and for passing the coke to a car or other receptacle with a minimum of breakage of the coke.

Other and further objects will appear as the description proceeds.

We have shown certain preferred embodiments of our invention in the accompanying drawing, in which-- Figure 1 is a plan view-of the coke receiving apparatus:

Figure A is an elevation of the apparatus shown in Figure 1; and

Figure 3 is a section taken on line ure 1.

The tray shown in Figures 1 to 3 for receiving the coked sheet or layer, includes a pan 26 provided with pairs of laterally extending lugs 21 and 28 which rest in notches formed in the topof the supporting members 29 and 30 carried by'the car 3| which is moved along the track 32 located 50 parallel to the front ofthe battery of ovens. The

cushioning means 33 are provided adjacent the support points for the pan. The cable 34 is hooked to the end of the pan toward the oven and passes over a pulley 35 carried by a'standard 55 36 coming down to drums 3'I driven by motor 38.

The left end of the pan, as shown, extends adjacent the walkway 39 located adjacent and level with the floors in the ovens 40. A removable member 4! may be placed to bridge the gap between walkway 39 andthe end of the pan 26. The pipe 42 extends across the point at which the sheet of coke enters the pan and serves to direct a spray of water downwardly on the hot mass of coke.

In the use of the apparatus it will be understood that the oven doors will be raised and that the pusher will be used to thrust the sheet or layer of coke out into the pan 26. This may be usually accomplished without serious breakage of the coke. As the layer passes under the spray from pipe 42, the coke is effectively quenched after having been only exposed to the air for a few seconds. This produces a coke of a more silvery appearance and the quenching of the coke in the layer brings about a more uniform quenching. The water is distributed crosswise of the charge through the area and any excess water which passes down through cracks in the coke is collected in the water-tight bottom of the pan. It will distribute equalize the temperature of the coke by producing steam which passes up through the coked mass and thus thoroughly deadens it. After the coke has been properly quenched, the pivoted pan is raised by hauling on the cables 34, and the coke slides into the conveyor, hopper, coke car or other receptacle for receiving it. By the use of this construction the necessity for an expensive coke receiving wharf is eliminated and the breakage ,of the coke is reduced both on account of its uniform quenching-and also by doing away with the greater portion of the rough handling which coke ordinarily receives.

While we have shown certain preferred embodiments of our invention, these are to be understood to be illustrative only, as we contemplate such changes and modifications as may be itself through the pan and.

necessary to meet varying conditions and requirements within the spirit and scope of the appended claims.

We claim: 1
